Design of Experiments
Design of experiments consists of a series of techniques used to explore various operating conditions of a process with the goal of finding lower costs of raw materials, process, and product; improved product performance; less variability in the product; or higher production capacity to meet increasing demand. In large companies with specialized departments, experimental design is the province of engineers, food scientists, or the research and development department. Quality control personnel may become involved with the performance, and possibly some of the evaluation of industrial experimentation. Consequently, an understanding of the techniques of this discipline is valuable. In smaller companies where the task of industrial experimentation often falls to the quality control manager, a knowledge of statistical design of experiments is imperative.
